<p><b>5.2.1 Simple (unlinked) service codes</b></p>

<p>Codes: Snt; cdt; pas; dsc; cms; Frh; Fer; Time;Location (Arrival <u>or</u> departure);
Time;Time;Location (Arrival <u>and</u> departure);</p>

<p>These codes are all independent of each other and independent of other codes.
Note that new trains (code Snt) may be stationary or moving, and may be started
under signaller control if required. This is done by adding ';S' after the Snt
line - e.g. <span style='color:blue'>Snt;146-12 147-12;S</span>. No further
lines except repeats are permitted for these entries.</p>

<p>Note that where minimum dwell times (MDTs) are included for arrivals, the timetabled dwell time (departure time - arrival time) should always exceed the MDT.  Failure to observe this will cause trains to run late and the 'Actions Due' panel (see section 6.10) to give inaccurate times.</p>
